1. Renewal

Note Let’s Encrypt CA issues short lived certificates (90 days). Make sure you renew the certificates at least once in 3 months.

In order to renew certificates simply call the letsencrypt (or letsencrypt-auto) again,
and use the same values when prompted.

You can automate it slightly by passing necessary flags on the CLI (see --help all),
or even further using the Configuration file.

If you’re sure that UI doesn’t prompt for any details you can add the command to crontab
 (make it less than every 90 days to avoid problems, say every month).

Please note that the CA will send notification emails to the address you provide if you do not renew certificates that are about to expire.

確かに「証明書の新規取得」と同じ手順で更新可能だった。
